Javascript 未捕获的TypeError:无法读取未定义的属性“createClass”

我一直在尝试在我的一个应用程序中使用react路由器。但是我越来越

Uncaught TypeError: Cannot read property 'createClass' of undefined

在线

var DefaultRoute = React.createClass({ ..

我一直在写的代码是

var Q                       = require('q'), 
    doThis                  = require('./generic/modules/doThis.js'),
    doThat                  = require('./generic/modules/doThat.js');
var React = require('react');
var Router = require('react-router');
var Route = Router.Route;
var Redirect = Router.Redirect;
var DefaultRoute = Router.DefaultRoute;

var aModule = require('./modules/aModule/aModule.js');
var Master = require('./modules/master/master.js');

var injectTapEventPlugin = require('react-tap-event-plugin');

(function (){

    var routes = (
        <Route name="root" path="/" handler={Master}>
            <Route name="time" handler={aModule} />
        </Route>);
    window.React = React;
    injectTapEventPlugin();

    var doThisPromise = doThis.init();
    doThisPromise.
    then(function() {
        doThat.init();
        Router.run (routes, function(Handler) {
            console.log('in router run');
            React.render(<Handler/>, document.body);
        });
    }, function (err) {

    });
})();

如有必要，请询问，我也将提供与路线相关的js

检查require'react'是否返回您期望的内容。此外，我在代码中的任何地方都没有看到DefaultRoute=React.createClass。我看到DefaultRoute=Router.DefaultRoute，它们应该是相同的吗？是的，react正在按照预期正确地进行安慰。DefaultRoute不是我的代码。这是react路由器代码。所以导致错误的代码在react-router中，而不是您向我们展示的代码？您使用的react和react路由器版本是什么？此外，请尝试卸下node_模块并重新安装。这是一个非常奇怪的问题。@SpencerWieczorek：基本上，是的：
